kmemtrace: Fix up tracer registration
Commit ddc1637af217dbd8bc51f30e6d24e84476a869a6 ("kmemtrace: Print binary output only if 'bin' option is set") ended up inverting the error detection logic. register_tracer() returns 0 on success, which this change caused to treat as an error, resulting in: [ 0.132000] Warning: could not register the kmem tracer as well as bailing out of the initcall with an error value. This restores the old logic.
